Human Body Based Appliances Control Using PIR & GSM


Review     here


The proposed auto detection of human done using the PIR sensor to indicate the entering or exit of the persons. Microcontroller continuously monitors the infrared receiver. When any object pass through the PIR receiver then the IR rays falling on the receiver are obstructed, this obstruction is sensed by the microcontroller also PIR sensor will check the presence of human beings with the help of radiations emitted by human beings. Then microcontroller will check the input coming from these and simultaneously if somebody is present then automatically checks for the light intensity. And then if the room is found dark it switches ON the lights s. And if nobody is present then all the lights will be switched off automatically.
